A kind of field bus called Actuator and Sensor interface bus(AS-i) was designed in this paper. The configuration of AS-i network system used Application Specific Integrated Circuit(ASIC) SAP5S chip and PLC S7-200 station, which included CPU 224 and AS-i master module CP 243-2. We also created an example program for PLC S7-200 to control AS-i network. The fire and smoke detection system was made with AS-i network system that was designed. This system had got more advantages than other system such as number of stations, easy installation, wide working area, etc. And designed system can be used as a partner network for higher level field bus networks.

The railway signaling system consists of several vital computerized equipments. Now the project for development of signaling system for the next-generation high-speed train is progressed according to the consortium. The developing signaling system by this project, kTCS(Korean Train Control System), is composed of kTCS-CTC, kTCS-IXL, kTCS-ATC and etc. The KTCS signaling has to be operated as a integrated system by interface between each signaling. To achieve these, communication protocols between each signaling have to be designed and message codes are defined. In this paper the configuration of integrated kTCS system and designed communication protocol is presented.

Human error has brought about accidents more than 50% in system of a large size and complicated expecially in nuclear power plants(NPPs). The technology of Man Machine Interface(MMI) has been changed to the digitalized controls employing computer-based technology. According to this trend. the human factors guidelines are becoming main issue for reliable supports to digitalized information displays. However. the existing human factors guidelines is not enough for advanced information display on NPPs. The purpose of this research is to develop the reliable design and evaluation guidelines for advanced information display in main control room (MCR) of NPPs. In this study. the various general human factors guidelines concerning information display on CRT are integrated on data base management system. unified based on the integration rules. and applied in computer based procedures. The use of the integrated guidelines are expected to evaluate the existing information display on MCR in NPPs from the human factors point of view.

Recently, business application vendors have responded to customer demand with several technological and organizational changes for reflecting network-oriented process flow with electronic communication and expanding their market. In organizational changes. Vendors are adding new functionality to their core offerings through mergers and acquisitions, or by partnering with front-office operation and SCM vendors. And technological changes are embracing the development of component-based application and middleware technology to be possible with integration of their function modules. We will present the design and development process of component-based SCM system to be integrated with heterogeneous ERP under implementation. Especially, we survey and analyze the technology related with CBD(Component-Based Development) to be adapted this research - component's design and methodology, the interface for component integration, middleware's development methodology of Enterprise Middleware vendo to bundle various types of middleware into a single package product with easy-to-use interface.

This paper describes the architecture and development of real-time monitoring system for ILRT (Integrated Leakage Rate Test). Object Oriented approach is used during the analysis and design. The architecture can be spited into two modules. First one is the Interface module, which, takes care of the communication between the server and the clients, and the second module is the Graphical User Interface (GUI) module, which takes care of the GUI in the web browser of the client. The technologies used includes Java, Java Bean and Java Applet. Etc.

Nowadays, the modeling of systems have been enabled by various models and methodologies that are used for different purpose and perspectives upon the systems. The integrated modeling methodology that integrates these models and methodologies has become challenging issues in system integration such as CIM and PDM. The primary objective of this paper is to propose the comprehensive integrated modeling methodology that integrates the Extended IDEF0 function model, OOIDEF0 information model, navigation model, interface model, and organization model for an effective analysis and design of the CIMS for ship production. This methodology can be used for the integrated system, and cover the systems development life cycle in an integrated fashion. In order to prove the consistency and efficiency of the proposed methodology, the CIMS for ship production is modeled.

Railway signaling systems consist of several vital computerized equipment such as CTC(Centralized Traffic Control), EIS(Electronic Interlocking System), ATC(Automatic Train Control) and so on. Currently, the project for development of railway signaling systems for the next-generation high-speed train is progressed according to the G7 project and railway signaling related several companies and research institute are joined this project consortium. The railway signaling systems, being developed in this project, called as a kTCS(Korean Train Control System), is composed of kTCS-CTC, kTCS-IXL, kTCS-ATC and etc. kTCS signaling systems have to be operated at the laboratory testing level as integrated signaling systems by interface between each railway signaling systems before railway field installation and revenue service. To solve this matter, communication protocols between each signaling equipment are designed and message codes for each defined protocols have defined. And also several equipment has developed for the railway integrated signaling systems for laboratory testing. We has plentifully tested and verified the designed protocols and the characteristics of integrated railway signaling systems with our developed each kTCS signaling equipment and communication protocols. In this paper, the integrated kTCS system including communication protocols is presented.

Today, offshore design field is concerned with system integration such as CIM(Computer Integrated Manufacturing), PDMS(Product Data Management System) and EDMS(Engineering Data Management System) in order to cope with the change of engineering specification as owner's requirements during construction stage of the project. This paper deals with the case study that describes about the efficient interface between material control system and 3D CAD system to support the design process in offshore industry using design rules involved the designer's knowledge. In this paper, we constructed an information system, called knowledge-based CAD interface systems, which is composed material code management system and 3D specification generator which automatically creates 3D catalogue anti specification by linking the material code, called short code, and the specification components of the 3D CAD system. As a result of the construction, it is possible to maintain consistency of the design process, and through reduction of the design processing time and improvement of the design process, competitiveness is improved.
